In GSM cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal .
Read moreWhat is UMTS network type?
UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps).
Read moreHow many carriers can be aggregated in LTE?
Since LTE Release 10 up to 5 component carriers may be aggregated, allowing for transmission bandwidths of up to 100 MHz. Using five aggregated component carriers, MIMO and 256QAM allows theoretical data rates of up to 2 gigabits per second.
Read moreHow many types of carrier aggregation are there?
As mentioned earlier, there are two types of carrier aggregation: contiguous; and non-contiguous. Non-contiguous carrier aggregation can be in the form of intra-band or inter-band. The different types of carrier aggregation will result in different deployment scenarios.
Read moreWhat is DL frequency?
In case of FDD (Frequency Division Duplex) LTE downlink channel (DL, eNB transmits UEs receive) and uplink channel (UL, UEs transmit eNB receives) are transmitted simultaneously on different frequencies. Also each band is marked by LTE release number where it was defined.
Read moreWhat is DL Earfcn in LTE?
EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number .In LTE, the carrier frequency in the uplink and downlink is designated by EARFCN, which ranges between 0-65535. EARFCN uniquely identify the LTE band and carrier frequency.
